* Makefile: Explicitly set '-std=c99'Edward O'Callaghan2021-01-131-1/+1
| | | | | | | | | | | | | | | | | | This matches the build flags that are correctly explicitly defined in meson.build where-as the Makefile is randomly picking up whatever the system toolchain happens to default to.

* Makefile: Add a DISABLE_CLOCK_GETTIME optionMartin Lucina2021-01-111-0/+5
| | | | | | | | | | | | | | Allows to force-disable the use of clock_gettime() at build time, falling back to busy-looping for udelay. This is useful when building for systems which are known to lie about the resolution of clock_gettime(), such as Linux guests running under the Muen Separation Kernel.

* s25f.c: implement probing and block erasers for SpansionNikolai Artemiev2020-12-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | This adds support for Spansion 25Fxxxxx chips. These chips require their own probing logic because the first 6 bytes returned by RDID must be examined to identify the chip. New erase functions are required as the chips support multiple sector layouts, and the default layout must be changed to be able to erase the entire flash. Adapted from cros flashrom at `9c4c9a56b6a0370b383df9c75d71b3bd469e672d`.

* Makefile: Fix building on AArch64 NixOSPyry Kontio2020-08-241-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The parsing of the output of archtest.c produced an unexpected value on AArch64 NixOS. For example, the make variable ARCH was set to: ``` bit outside of fd_set selected arm ``` This made the arch and OS checks fail. This commit simplifies the parsing, making it more robust. The C files archtest.c, endiantest.c and os.h used to set the TARGET_OS, ARCH and ENDIAN variables, respectively, output the result of the test as the final line, so just extracting the final line and removing double quoting is enough. This commit also fixes a bug with debug_shell lacking escaping single quotes, which prevented using the single quote in the debug_shell calls. It used to work by accident before this fix; the line in the call happened to contain a balanced pair of double quotes and lacked other characters that needed escaping, which didn't break the debug_shell, but this was accidental and very brittle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flashmap, or simply fmap, is a binary data format for describing region offsets, sizes, and certain attributes and is widely used by coreboot. This patch adds support for the fmap data format version 1.1 and adds --fmap and --fmap-file arguments. Using --fmap will make flashrom to search the ROM content for fmap data. Using --fmap-file will make flashrom search a supplied file for fmap data. An example of how to update the COREBOOT region of a ROM: flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT The fmap functions are mostly copied from cbfstool. Currently it is made mutually exclusive with other layout options until we are more clever about this input.

| | | | | | | | | | | | | | | | | | | | | | | | The 96Boards Developerbox (a.k.a. Synquacer E-series) provides a CP2102 debug UART with its GPIO pins hooked up to the SPI NOR FLASH. The circuit is intended to provide emergency recovery functions without requiring any additional tools (such as a JTAG or SPI programmer). This was expected to be very slow (and it is) but CP2102 is much cheaper than a full dual channel USB comms chip. Read performance is roughly on par with a 2400 baud modem (between 60 and 70 minutes per megabyte if you prefer) and write performance is 50% slower still. The full recovery process, with backup and verification of 4MB data written takes between 14 and 15 hours. Thus it is only really practical as an emergency recovery tool, firmware developers will need to use an alternative programmer.

* digilent_spi: add a driver for the iCEblink40 development boardLubomir Rintel2018-06-261-0/+10
| | | | | | | | | | | | | | | This is driver that supports the Lattice iCE40 evaluation kits. On the board is a SPI flash memory chip labeled ST 25P10VP. Tested to work read/write/erase with "-p digilent_spi -c M25P10" or with a patch that resets the part beforehands (in which case it gets detected as a M25P10-A and is way faster due to paged writes).

But practical concerns (i.e., bugs) have meant we don't quite do this. For reads: Bug https://b/35573113 shows that some SPI-based MTD drivers don't yet handle very large transactions. So we artificially limit this to block-sized chunks. For writes: It's not clear there is a hard limit. Some drivers will already split large writes into smaller chunks automatically. Others don't do any splitting. At any rate, using *small* chunks can actually be a problem for some devices (b:35104688), as they get worse performance (doing an internal read/modify/write). This could be fixed in other ways by advertizing their true "write chunk size" to user space somehow, but this isn't so easy. As a simpler fix, we can just increase the loop increment to match the read loop. Per David, the original implementation (looping over page chunks) was just being paranoid. So this patch: * clarifies comments in linux_mtd_read(), to note that the chunking is somewhat of a hack that ideally can be fixed (with bug reference) * simplifies the linux_mtd_write() looping to match the structure in linux_mtd_read(), including dropping several unnecessary seeks, and correcting the error messages (they referred to "reads" and had the wrong parameters) * change linux_mtd_write() to align its chunks to eraseblocks, not page sizes Note that the "->page_size" parameter is still somewhat ill-defined, and only set by the upper layers for "opaque" flash. And it's not actually used in this driver now. If we could figure out what we really want to use it for, then we could try to set it appropriately.

* Add support for the ENE Embedded Debug Interface EDI and KB9012 ECPaul Kocialkowski2018-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The ENE Embedded Debug Interface (EDI) is a SPI-based interface for accessing the memory of ENE embedded controllers. The ENE KB9012 EC is an embedded controller found on various laptops such as the Lenovo G505s. It features a 8051 microcontroller and has 128 KiB of internal storage for program data. EDI can be accessed on the KB9012 through pins 59-62 (CS-CLK-MOSI-MISO) when flash direct access is not in use. Some firmwares disable EDI at runtime so it might be necessary to ground pin 42 to reset the 8051 microcontroller before accessing the KB9012 via EDI. The example of flashing KB9012 at Lenovo G505S laptop could be found here: http://dangerousprototypes.com/docs/Flashing_KB9012_with_Bus_Pirate Change-Id: Ib8b2eb2feeef5c337d725d15ebf994a299897854 Signed-off-by: Mike Banon <mikebdp2@gmail.com> Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-on: https://review.coreboot.org/23259 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>
